A few days ago I got the message that /boot is full.
I went ahead and did some cleanup according to some stackoverflow posts, removed old kernel versions 5.4.X, now there is space again.
Everything seemed to work that day. But a day later sound and microphone stopped working.
I am running kernel version 5.8.0-55-generic
When booting, after I login, the screens now stay black for an extended period of time (maybe 30 seconds? 60?, waaaaay longer than before)
After it finally shows the desktop the sound icon in the tray is crossed out. Opening it shows:
First no devices at all, the list is completely empty.
After a while of system uptime some devices start to show.
Right now it shows various HDMI outputs, headphones and digital audio. An hour ago it also showed the internal speakers. They did not work however. After some fiddeling the internal speaker is not displayed at all anymore.
Only the HDMI outputs work, some of my monitors have speakers, those work.
For Input devices only the built-in microphone is showing, but it seems to not work, it gets detected by chrome, but a microphone test site I have used before now shows complete silence from the microphone.
Some info output:

I've searched around already and tried a bunch of things:
echo "options snd-hda-intel model=generic" | sudo tee -a /etc/modprobe.d/alsa-base.conf
echo "options snd-hda-intel dmic_detect=0" | sudo tee -a /etc/modprobe.d/alsa-base.conf
echo "blacklist snd_soc_skl" | sudo tee -a /etc/modprobe.d/blacklist.conf
None of this helped, I removed the entries from the config files afterwards.

reboot
sudo apt-get install --reinstall alsa-base pulseaudio
sudo alsa force-reload
reboot
rm ~/.config/pulse/ -rf
reboot
None of these things changed anything at all, sound and microphone stay silent.
What can I do?
EDIT:
Maybe a week after the problem showed up, it has now magically vanished, everything works again. I am confused.
